Hi There,
I owned Honda Accord 2007 - 2.0 IVTEC its brand new car when I bought them.
After few month down the road, I foreseen this issue:
CAR IDLE Problem

The car had problem on IDLE.
When I start the car
1. The idle is normal above 500rpm
2. When the automatic aircond cuts in or out & with or without the gear is engaged the idle will drop to below 500rpm.
3. When the automatic aircond cuts in or out & with or without the gear or with/without the normal radiator fan cuts in or out the idle will drop to below 500rpm.
4. With the all the aircond/lights/gear engaged mode the idle drops to below 500rpm its alot of discomforted because you can see the stering/the entire car will be vibrating.

When I reported this to Honda Service Center they did this fix but it wasnt solve
1. Clean the throttle - slight improvement - but the problem back again
2. Change the engine mounting - no improvement - but the problem back again
3. Adjusted the Idle setting manually to 800rpm - but the problem back again.
They said they have adjusted the GCON setting to adopted the new engine tuning setting

All this doesnt help at all. Thats why I'm referring to your all.

Its shame to know this happen to brand new car with mileage of 50K km.

Pls assist me what else I should check or I can bring forward to them to check on.

The car driving this fine but the idle makes me uncomfortable and uneasy because it wasnt the case before.

I dont know whether this is manufacture defect. But strange it wasnt seen when I got the car as brand new.

Your assistance much appreciated.
Thanks
